PSYCH 100 Lecture Notes - B. F. Skinner, Reinforcement, Classical Conditioning
Document Summary
Pavlov believed both conditioned and unconditioned stimuli are paired close together in time = and active same area of the brain. Voluntary behavior learned through the effects of pleasant consequences and unpleasant consequences. Responses followed by pleasurable consequences are repeated. Responses followed by unpleasurable consequences are not repeated. Ex. bad sex, never do it again with the person. Reinforcement: any event or stimulus that when following a response increases the probability that the response will happen again. Positive reinforcement: addition of a pleasurable stimulus (adding) Negative reinforcement: removal escape or avoidance of aversive stimulus (removing) Taking away something undesirable to increase behavior. Partial reinforcement: response is reinforcement after some but not all. A stronger response to build, less sustainable to things like extinction. Conditioned: (better for new behavior) response is reinforced after all responses.
